RE: Carbon Express Maxima 250's or 350's
Maxima's are a great shooter, very consistant, best I have. However, they will break, my brother and I broke 5 350s last season. They just snap right in to and the finish is the worst of any I've ever shot. There's no reason they can't be silent coated for the money, I dipped mine.
I'd try the 250 first, or and better yet get 6 of both and sell the one's that don't work just make up one of each.
Tried fmj's and acc's this year so far, neither makes me want to scream from the roof tops about them either, good, kind of boring and the finish also is noisie. The quietest shaft I have is the beman ics hunter elite. When you pull one of these you know what quiet is and in a hunting arrow there really no excuse for a noisie one. Almost as quiet as cutting through warm butter.
